Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,656/75,000,000,002
- The integer number above the bar is called numerator: 41,666,666,656
- The integer number below the bar is called denominator: 75,000,000,002
- The fraction bar means that the numerator is divided by the denominator.
- To get the fraction's value divide the numerator by the denominator:
The value = 41,666,666,656 ÷ 75,000,000,002
To reduce a fraction to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF
To calculate the greatest common factor, GCF:
- 1. Factor the numerator and the denominator (into prime factors), build their prime factorizations.
- 2. Multiply all their common prime factors, taken by the lowest exponents.
1. Factor the numerator and the denominator:
To factor a number (into prime factors) - or, in other words, to break it down to prime factors - or, in other words, to build its prime factorization: find the prime numbers that multiply together to get that number.
The prime factorizations:
Written with exponents:
41,666,666,656 = 2 × 2 × 2 × 2 × 2 × 83 × 251 × 62,501 = 25 × 83 × 251 × 62,501
41,666,666,656 is a composite number.
75,000,000,002 = 2 × 17 × 36,563 × 60,331
75,000,000,002 is a composite number.
41,666,666,656/75,000,000,002 =
(41,666,666,656 ÷ 2) / (75,000,000,002 ÷ 2) =
20,833,333,328/37,500,000,001
Yet another method to reduce the fraction
To reduce a fraction without calculating the GCF: factor its numerator and denominator, then all the common prime factors are easily identified and crossed out.
41,666,666,656/75,000,000,002 =
(25 × 83 × 251 × 62,501)/(2 × 17 × 36,563 × 60,331) =
((25 × 83 × 251 × 62,501) ÷ 2) / ((2 × 17 × 36,563 × 60,331) ÷ 2) =
(24 × 83 × 251 × 62,501)/(17 × 36,563 × 60,331) =
20,833,333,328/37,500,000,001
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
20,833,333,328/37,500,000,001 =
20,833,333,328 ÷ 37,500,000,001 =
